This is based on ISY v2.8.16 and Kubuntu but should work for most Linux's.
First read the instruction for the release of ISY 2.8.16:
THIS IS NOT A RECOMMENDED WAY TO RUN THE ADMIN CONSOLE
Speaking from experience this method is fragile and will produce odd results when the version of the jre or console change. But that being said I hate having to have a browser window open in order to having the admin console running. Also I am also assuming if you are running Linux, you have basic computer competency and accept that anything going wrong using this is your fault.
So this is what I did:
1) Set your browser association so that jnlp files are either saved or prompted then go to:
http://www.universal-devices.com/99i/2.8.16/admin.jnlp
and save the file to somewhere you would like to keep it.
2) Now edit the file and replace www.universal-devices.com/99i/2.8.16 with your ISY IP address and save it.
3) Now you have to run it with the right javaws. Java under Linux is sometimes a little wierd with OpenJDK vs Sun. So I had to call the right javaws with full pathing. My Sun javaws was located:
/usr/lib/jvm/java-6-sun-1.6.0.24/bin/
So when I was setting up the icon the command line is:
/usr/lib/jvm/java-6-sun-1.6.0.24/bin/javaws admin.jnlp
with the working folder being where the admin.jnlp is. With this command line you should see a Sun Java splash screen before the admin console runs (this is good). If you want to suppress the splash add the -Xnosplash to the command line (the X is not a typo)
If you launch the console and the little sun or moon icons are not next to the sunrise sunset time or the status of your devices does not display, you have something wrong.
I hope this helps those few Linux geeks out there.
